d1i1m1o1n [39]

Answer:

$\frac{BC}{DC}=\frac{AC}{EC}$

$\frac{20-x}{x} =\frac{21}{7}$

$\frac{20-x}{x} =3$

$20-x=3x$

$4x=20$

$x=5$

$So, CD=5$

What is the circumference of circle P? Express your answer in terms of pi. PC= 17 cm.

Sedbober [7]

I am assuming that PC is a radius.

d = 2 * PC = 2 * 17 = 34

C = pi * d
C = pi * 34 = 34pi cm

if PC is a diameter, the change the 34 into 17.

A triangle has the following vertices (-1,1), (6,-2)and (3,5) if the scale factor of 3, what will be the vertices of the image

olga2289 [7]

Answer:

a. (-3,3), (18,-6), (9,15)

Step-by-step explanation:

If the scale factor is 3 and dilation is about the origin, each of the coordinates of the pre-image is multiplied by 3 to get the coordinates of the image.

Multiplying (-1, 1) by 3 gives (-3, 3), which matches choices A and C.

Multiplying (6, -2) by 3 gives (18, -6) which matches choices A and D.

The only viable choice is choice A.
